There's an RDS server that has been in production for more than a year, the licensing server is on the same machine. It's functional at this time (new clients can remote in and receive licenses, and reports of this activity can be pulled from the RD Licensing Manager.
However, neither the licensing diagnosis nor the licensing manager (or any other RDS related tool or snap-in) shows any installed licenses.
Licensing manager has an entry for "Windows 2000 Server - Built-in TS Per Device CALs" (all servers are 2008r2, not sure why the mention of server 2000)
At the bottom of the Licensing diagnosis it reports the correct details of the licensing server:
Credentials: Available
Connectivity: Available
Version: Windows Server 2008 R2
"Prevent License upgrade": Not Enabled
"Licensing server security group": Not enabled
Per User Tracking and reporting: Available
But under "The license server has the following licenses installed and available", it reports:
"No licenses are installed on this license server"
Licenses HAVE been installed in the past, and in fact the server is behaving as if they're installed now (properly issuing licenses to clients), but everything I look at here says otherwise. My biggest concern with this that we'll need to pull a certain amount of those licenses off onto another server in the next few weeks, and i'm hesitant to do so when it's in this inconsistent state.
What are my options for troubleshooting/resolving this sort of an issue? Also, what of those can I perform without interrupting service?
